Multiselect menus enable users to select multiple items from a list simultaneously, offering flexibility and enhanced control. Here are common methods for enabling multiselect functionality:

• Utilize hotkeys such as Shift, Command, or Control in conjunction with mouse clicks
• Use checkboxes to mark desired options
• Implement a tagging system, where clicked items appear as tags at the top

To simplify decision-making, make selected items prominently visible, thereby reducing cognitive load. However, it's worth noting that multiselect menus can be challenging to implement effectively on mobile platforms due to space constraints.
